Prusa Measuring Wheel
prusaprinters
<p>Its a measuring wheel that you can use outdoors to measure the long distances traveled instead of the traditional measure tape. basically its a construction measuring tool. The wheel rotates and, using basic rotational kinematics (s=rθ), you can determine the distance between two points.After completing the project you will have a nice LCD screen showing you the distance in meter that you can show off your skills in 3d printing and electronics. Enjoy.</p> <h3>Print instructions</h3><p>If you are looking for practical and useful project to show off the power of your 3d printer, this project is for you. once you have print and assembly the project you will have a complete product that you can use any time. The Prusa measuring wheel can be used to measure long distance easily without the assistance from others. The project can be printed easily and the long beam is sliced and can be staked due to the tight snap fits and you can make as long as you need. Also, if you want to add more rigidity to it you can weld the edges of the beams with a soldering iron . The electronic and the code is actually easy and a good way to learn about electronics. I have wrote below all the required information for you to build your own Prusa Measuring Wheel. Also, you should find the code, part list and exploded view of the parts in the pictures to understand how thing should be assembled . If you like my project please like and comment , also you can visit my Instagram page “ HAZ_innovations “ which i will make more similar projects in the future. Thank you and enjoy.</p> <p>Benefits :<br/> 1- Very useful and practical project.<br/> 2- Easy to print ( The long beam is sliced and tight snap fitted together )</p> <h3>3- Easy Electronics wiring and programming</h3> <p>wiring the circuit :</p> <h3>Wiring diagram is in the picture list ,its easy to make using the picture as a reference. </h3> <p>Parts required in the pictured attached. but i will listed below the links:</p> <p>1-Arduino nano :<br/> <a href="https://www.newark.com/arduino/a000005/dev-board-atmega328-arduino-nano/dp/13T9275?COM=ref_hackster">https://www.newark.com/arduino/a000005/dev-board-atmega328-arduino-nano/dp/13T9275?COM=ref_hackster</a></p> <p>2- LCD :<br/> <a href="https://www.newark.com/adafruit-industries/181/standard-lcd-16x2-extras-white/dp/53W5770?COM=ref_hackster">https://www.newark.com/adafruit-industries/181/standard-lcd-16x2-extras-white/dp/53W5770?COM=ref_hackster</a></p> <p>3- Rotary Encoder :<br/> <a href="https://www.banggood.com/KY-040-Rotary-Decoder-Encoder-Module-AVR-PIC-p-914010.html?gmcCountry=SA&currency=SAR&createTmp=1&utm_source=googleshopping&utm_medium=cpc_bgs&utm_content=frank&utm_campaign=frank-ssc-sa-en-all-0618feed&ad_id=443067658277&gclid=CjwKCAjwsO_4BRBBEiwAyagRTSfvVzsN0TSDPExLmu3hl5uoKxZSBRgoOngfBFojzgYHeJ4JCQCA8BoCL6IQAvD_BwE&cur_warehouse=CN">https://www.banggood.com/KY-040-Rotary-Decoder-Encoder-Module-AVR-PIC-p-914010.html?gmcCountry=SA&currency=SAR&createTmp=1&utm_source=googleshopping&utm_medium=cpc_bgs&utm_content=frank&utm_campaign=frank-ssc-sa-en-all-0618feed&ad_id=443067658277&gclid=CjwKCAjwsO_4BRBBEiwAyagRTSfvVzsN0TSDPExLmu3hl5uoKxZSBRgoOngfBFojzgYHeJ4JCQCA8BoCL6IQAvD_BwE&cur_warehouse=CN</a></p> <p>4- Single Turn, Cermet, Top Adjust, 10 kohm :<br/> <a href="https://www.newark.com/bourns/3362p-1-103lf/trimmer-potentiometer-10kohm-1turn/dp/62J1882?COM=ref_hackster">https://www.newark.com/bourns/3362p-1-103lf/trimmer-potentiometer-10kohm-1turn/dp/62J1882?COM=ref_hackster</a></p> <p>5- Resistor, 221 ohm :<br/> <a href="https://www.newark.com/vishay/cmf50221r00fheb/metal-film-resistor-221-ohm-250/dp/67P6474?COM=ref_hackster">https://www.newark.com/vishay/cmf50221r00fheb/metal-film-resistor-221-ohm-250/dp/67P6474?COM=ref_hackster</a></p> <p>6- Long Wires:<br/> <a href="https://www.amazon.com/32-8ft-Extension-Cable-Connector-Colour/dp/B07DZ5W1P9/ref=sr_1_2?dchild=1&keywords=22+AWG+RGB+Extension+Cable+Line&qid=1595723166&sr=8-2">https://www.amazon.com/32-8ft-Extension-Cable-Connector-Colour/dp/B07DZ5W1P9/ref=sr_1_2?dchild=1&keywords=22+AWG+RGB+Extension+Cable+Line&qid=1595723166&sr=8-2</a></p> <p>7- Bearing :</p> <h3><a href="https://www.amazon.com/SKF-Precision-Shielded-Non-Contact-Clearance/dp/B0071AU30E/ref=sr_1_3?dchild=1&keywords=bearing+skf+6303&qid=1595723275&sr=8-3">https://www.amazon.com/SKF-Precision-Shielded-Non-Contact-Clearance/dp/B0071AU30E/ref=sr_1_3?dchild=1&keywords=bearing+skf+6303&qid=1595723275&sr=8-3</a></h3> <p>Coding :</p> <p>picture of the coding is attached in the picture just copy and upload it to your Arduino nano. the main equation used in hte code is the Perimeter : (2<em>Pi</em>R/N).<br/> So the only thing that you want to change if you want to explore your options is N and R values which they are<br/> N = number of encoder steps and it depend on your encoder you have used<br/> R= is the radius of the prusa spool radius , change it if you want use different scale disk.</p>
